3mm Rx7 Cryogenically Treated Solid Corner Seal Set (ARE89-C)

(12) Cryogenically Treated 3mm Solid Corner Seals for use on all 12A and 13B 3mm applications.

See our Cryogenically Treated FAQ

This is an excellent upgrade to any engine. These are desirable under high boost or nitrous applications. This was designed by David Atkins and has been patented.

This is a one piece corner seal. These can be used in place of the 2 piece Mazda corner seals with plugs. Can be used with the wire type corner seal spring, the rx8 type corner seal springs, or the 93-95 HP wafer type spring, which is recommended.

Mazda basically copied our design with the Rx8, getting rid of their faulty rubber corner seal plug and opting for a steel one basically making their corner seals solid like these.

Do not use these with lapped side housings.
